摘要

摘要: 采用2种不同编织形式的经编织物经过热压成型制备了连续玻纤增强聚丙烯(GF/PP)复合材料,并利用扫描电子显微镜对该复合材料的浸渍状态微观形貌和空隙率进行了分析.同时研究了织物结构对复合材料浸渍性能的影响,讨论了影响复合材料力学性能的因素及其变化规律,比较了2种织物的编织形式.结果表明,经编织物法是制备热塑性复合材料的可行途径;不同织物形式具有不同的浸渍性能,直接影响复合材料的力学性能.

Abstract: Continuous glass fiber reinforced polypropylene (GF/PP) composite material were manufactured with a new kind of warp-knitting fabrics in two different forms by thermoforming. The microstructure of impregnation quality of the composite material was observed with the scanning electronic microscope (SEM) and substantiated by the results of void content measuring. The fabric structure effects on impregnation quality were investigated. The composite mechanical properties influencing factors and change tendency were also discussed. The two different fabric forms were compared. The results show that it is feasible to manufacture thermoplastic composite materials with warp-knitting fabrics; different knitting forms lead to different impregnation quality which directly influences composite mechanical properties.
